Hi Roy, this is the site where I bought the optical sensor YxRobot: http://www.plexishop.it/en/arduino/sensori-per-arduino/angular-position-transducer-optical-encoder.html Its cost was about 5 Euro incl. tax. It is an Italian shop-website.

Hello Roy. Here are pictures of the sensor YwRobot used by me and my trial version of your turntable project. Tomorrow I will receive two "hall effect sensor", so I can check which of the two systems for detecting the zero point seems more accurate. Greetings. Turntable Sensor in action Sensor side back

Hi Roy. Tomorrow evening I take a picture of the prototype. For now I can tell you that the optical sensor is a YwRobot. Angular position transducer, optical encoder On the radio photoelectric sensor; speed sensor B infrared counting sensor; sensor module. A pulse signal is issued when the sensing area of the infrared light is cut off, i.e. A paragraph count, speed sensor. Motor speed sensor, the robot making essential. The use of infrared light detection, anti-interference ability. Schmitt trigger, high sensitivity, stable performance; suitable for motor speed measurement, workpiece count. Operating voltage 5V, black line output low, output high white line With fixed bolt hole for easy installation A pulse signal is issued when the sensing area of the infrared light is cut off. Specifications: Output low when the beam is interrupted Power supply: 5VDC Strip Connection: 2.54mm Dimensions: 32 x 11 x 20 mm LED indicators: - power presence - status indicator output Connection mode: 1. VCC 2. GND 3. OUT Digita il testo o l'indirizzo di un sito web oppure traduci un documento. Annulla Forse cercavi: A Domani. See you tomorrow. Rovilazz

Ray, I have to give you some good news: I've made for your test project. I just replaced the Hall Effect Sensor (RS370-6896) with an infrared optical sensor that I bought long ago on e-Bay. The magnet has been replaced by a thin object that with the rotation of the bridge goes to interpose the sensor fork. I did not even have to change your sketch!. It all works very well, for the time being commanded by Intellibox from Uhlenbrock (first version). MANY THANKS FOR THE HELP!!!!!! You did not think even you add a seven segment display to signal the position? Rovilazz

Good giornagiorno. First of all, thanks to everyone for the effort put in the projects presented in this tread! In particular, Ray, I tried to implement your project, but loading the sketch in ArduinoUNO me the following error is reported: sketch_feb07b.cpp.o: In function `__static_initialization_and_destruction_0': C:\Programmi\Arduino_1.0.5/sketch_feb07b.ino:50: undefined reference to `AccelStepper::AccelStepper(void (*)(), void (*)())' sketch_feb07b.cpp.o: In function `loop': C:\Programmi\Arduino_1.0.5/sketch_feb07b.ino:208: undefined reference to `AccelStepper::run()' sketch_feb07b.cpp.o: In function `BasicAccDecoderPacket_Handler(int, unsigned char, unsigned char)': C:\Programmi\Arduino_1.0.5/sketch_feb07b.ino:139: undefined reference to `AccelStepper::moveTo(long)' sketch_feb07b.cpp.o: In function `setup': C:\Programmi\Arduino_1.0.5/sketch_feb07b.ino:164: undefined reference to `AccelStepper::setMaxSpeed(float)' C:\Programmi\Arduino_1.0.5/sketch_feb07b.ino:165: undefined reference to `AccelStepper::setAcceleration(float)' Someone is able to suggest a solution? Thank you very much & greetings. Rovilazz

Hello Mr. Tender. I have recently discovered this forum and I'm curious about your project. I have to make a small turntable (for DCC) in HOm scale reproduction of a small Italian station, which no longer exists in reality. Your project would be just perfect for me !. I have already procured the Adafruit Motor Shield v.2 When you manage to complete the 7 part of your good project?. Big thumbs up from me for your idea. Greetings. (sorry for my english ...)
